Spectra of normalized volumes of right-angled hyperbolic polyhedra
A. Egorov, A. Vesnin
We consider three-dimensional hyperbolic polyhedra of finite volume with finitely many vertices. The normalized volume of a polyhedron is the ratio of its volume to the number of v…

The minimal covolume right-angled Coxeter group in hyperbolic 3-space
A. Egorov, A. Vesnin
We prove that among all right-angled Coxeter groups in hyperbolic 3-space, the group generated by reflections in the faces of a right-angled triangular bipyramid with three ideal a…
